Unknown keywork "--toml"

[Syize]

In the plugins page of fpm toturial, it says I can use the following command to generate the necessary dependency line:

fpm search --toml M_CLI2

and its output should be like:

M_CLI2 = { git = "https://github.com/urbanjost/M_CLI2" }

But it raises an error instead:

UNKNOWN LONG KEYWORD: --toml
KEYWORD        SHORT PRESENT VALUE
